To all whom it may concern:

Be it known that I, WILTON S. SCHUYLER, a citizen of the United Statesof America, and a resident o'fCincinnati in the county of Hamilton andState of Ohio, have invented a new and useful Improvement in anAccelerator for Combustion Engines, of which the following isaspecification.

An object'of my invention is to provide a simple and eflicientaccelerator that may be applied to motor vehicles.

Another object of my invention is to provide a device wherein the actionof the ordinary hand throttle is in no wise affected by the attachmentof a device embodying my invention to-the carbureter.

Another object of my invention is topro-- vide a device that maybereadily mounted upon motor vehicles and that will provide a firm andsubstantial support to the operators foot.

These and other objects are attained by the means described herein, anddisclosed in the accompanying drawings, in which:

Fig. 1 is a fragmental perspective view of a motor vehicle havingmounted on it a device embodying my invention.

Fig. 2 is a side elevation of a foot lever forming a detail of myinvention.

Fig. 3 is an end view of the device shown in Fig. 2.

v v Fig. 4 is a plan view of a plate and actuating means associatedtherewith, all of which form details of my invention.

Fig. 5 is a side elevation of the device shown in Fig. 4;.

Fig. 6 is an elevation of a carbureter control arm having mounted on ita device'em- I have disclosed my invention as applied to a Fordautomobile. The free end 8 of the carbureter arm 7 is in the ordinaryFord structure connected with a hand throttle by means of a suitableconnection. It is customary to provide the end 8 of the carbureter. armwith a bore in which such throttle end engages. In applying my devicethe throttle connection is disconnected from the arm 7 and the plate 9is secured upon the arm 7 by passing a suitable bolt '11 through a boreprovided therefor in the plate 9 and lodging in the bore in the end 8 ofthe arm 7. The" plate 9 has formed on it depending lugs 12 and 13 thatstraddle the frame 31. crank '32 that is pivotally connected'to the orCINCINNATI, oHIo.

direction in which the arm 7 is capable of it abar 14 that is pivoted'at15 upon the plate 9 and is provided at its free end with an aperture 16for the reception of the throttle rod connector that was removed fromthe bore in the end 8 of the carbureter arm reciprocating pin 17 has itsone end 18 -pivotally mounted'npon a stud 19 carried by the bar 14:. Theplate has anupwardly extending flange 20 provided with an aperturethrough which the pin 17 may be reciprocated. A washer 21 is mounted onthe pin 17 adjacent its pivotally mounted end, and a spring 22 mountedon the pin 17 has its opposite ends in abutment upon the washer 21 andthe flange 20. Alug 23 struck upwardly from the plate 9 limits themovement of the bar let under the influence of, the spring 22'. Theplate is provided with an aperture 24: for the reception of one end of aconnecting rod 25 extending forwardly from the foot pedal 26. The rearend of the connecting rod 25 has .a sliding pivotal mounting upon a pin27 pivotally mounted at the lower end 28 of an arm 29 fixedly carried atone endof a crank shaft 30 extending transversely of the foot lever Thecrank shaft 30 carries a lower end of a reciprocating plunger 33 carriedby a lateral extension 34 formed on the frame 31. A suitable head 35formed on the upper end of the plunger 33 is adapted to be engaged by anoperators foot and 1 to be moved downwardly through an open ing in thelateral. extension 34L through whichthe plunger reciprocally extends,and against the yielding resistance of the spring 36 having its oppositeends in abutment on the lateral extension and the head 35. laterallyextending foot rest 37 extends upwardly and sidewardly on the frame andis adapted to be contacted by an operators foot whereby to give asubstantial and rigid support to the operators foot adjacent the head ofthe plunger.- The frame 31. has formed on it rearwardly extendinglugs 38and 39. The lug 38 is adapted to be mounted directly upon the housing 40of the vehicle transmission and lug 39 has pivotally mounted on it alink, 41, the, link being adapted to have its one end secured upon thetransmission housing 40. When the device is oun ed one vehicle the 1 0 brds at the vehicle are disposed substantially at the upper end of thelateral extension 34 thereby protecting the transversely extending crankshaft 30 and the parts associated therewith from maltreatment.

In the operation of my device the downward pressure of an operators footon the plunger serves to rotatably actuate the crank shaft 30 whichmotion is utilized for pulling the connecting rod 25 rearwardly. Theforward end of the connecting rod, being connected with the plate 9serves to move the plate in a counterclockwise direction, see Figs. 1and 4;. During the movement of the plate under the influence of the footpedal, the bar 14- connected with the handle throttle remains stationarybecause of its connection with the hand throttle. The spring 22yieldingly resists movement of the plate 9. The spring 36 yieldinglyresists 'movement of the foot pedal. When the hand throttle is actuatedthe engagement of the bar 14 upon the lug 23 serves to transmit motionfrom the bar to the plate. At such times the connecting rod 25 is freeto slide through the pin 27 thereby avoiding binding of any of the footpedal parts and the connecting rod 25. It should be noted that operationof the carbureter by either the foot accelerator or the hand throttlewill not actuate the other carbureter control means. vThe foot pedalstructure, comprising the frame 31 gives a solid and substantial supportfor the operators foot and pre eludes pulsating of the carbureter valvebecause of any vibration of the vehicle body.
